以前,Welford和Baird曾报道过纽约市居民骨灰中的铀含量为22μg/kg。但他们所用的样本并不是取自纽约市的居民,而是取自饮用水中含有高浓度铀的美国中西部地区的居民,故此数据不能代表纽约市居民的实际情况。我们采集了纽约市事故牺牲者的一批脊椎骨、肺、肝和肾样本,分析结果表明纽约市居民骨中铀含量的估算值比上述数据要低10 Previously, Welford and Baird reported that uranium content in New York City residents’ ashes was 22 μg / kg. But the samples they used were not taken from New York City residents, but from residents of the Midwestern United States, which contained high concentrations of uranium in their drinking water, so the data do not represent the realities of New York City residents. We collected a sample of vertebrae, lungs, liver and kidney from victims of the New York City accident and found that estimates of uranium in New York City residents were 10 less than the above data
